DESCRIPTION
The LX5122 Plug and Play UltraMAXTM terminator represents next-generation technol ogy for SCSI termination applications. The low-voltage BiCMOS architecture employed in its design offers superior performance to older passive and active techniques.
Linfinity's architecture employs high speed adaptive elements for each channel, providing the fastest response possible. The channel bandwidth is typically 35MHz. The LX5122 compares favorably to older linear regulator approaches whose bandwidth's are dominated by the output compensation capacitor and are limited to the 500KHz bandwidth region (see further discussion in the Functional Description section). Linfinity's architecture also eliminates the output compensation capacitor typical in earlier terminator designs. Each is approved for use with SCSI-1, -2, -3, ULTRA and beyond — providing the highest performance alternative available today.
